Design Failure Mode and Effects Analysis (DFMEA) for Automotive Safety Systems

In this paper is presented an effective application of Failure Modes and Effects Analysis (DFMEA) in product design stages specific to vehicle safety systems. The scope of DFMEA is to eliminate as early as possible the design faults that could lead to the defective products. The potential failure modes, its causes, and effects are identified and severity, likelihood and detection are quantified in order to provide the corrective actions before first production run occurs. The results analysis for optimized stage indicate that all the analysed characteristics have a priorityrisk level (RPN) located in the medium and low risk areas, which means an improvement of the design process performance.
